To all whom it may concern:

Be it known that I, CARL A. DAHLBERG, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in l/Vindow-Boxes, of which the following is a specification.

This invention relates to improvements in a window box for the reception and retention of articles of foods of various kinds, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a box or receptacle of the above named general character, wherein articles of food may be kept, in moderate weather, without employing ice, in a wholesome and sanitary condition, and which box can be thoroughly ventilated in such a way as to exclude dust and insects, yet so as to create a circulation of external or pure air continuously therethrough, if desired.

A further object is to provide a window box which shall be simple and inexpensive in construction, strong, durable, efficient in operation, with its parts so made and arranged, that it can be readily fitted to window casings of different sizes, and in such a manner as to prevent the passage or entrance of rain, dust or wind between the supporting frame of the box, and the window casing within which the box is mounted.

Various other objects and advantages of the invention will be disclosed in the subjoined description and explanation.
